How To Say Hello In Japanese

The most common and well-known way to say hello in Japanese is:

こんにちは (konnichiwa)

You’ll hear this greeting used in various situations throughout the day, typically from midday to early evening, and it’s generally suitable for both formal and informal settings, but you’ll mostly hear it in formal settings (it’s weird to say it to your friends).

Konnichiwa is not commonly used as an early morning greeting.

Etymology and breakdown of konnichiwa

The term こんにちは (konnichiwa) has an interesting etymology:

It’s derived from 今日は (kon nichi wa), which translates to “as for today”.

Historically, this phrase was part of a longer greeting where the rest of the sentence was implied or understood based on context.

Here’s a breakdown:

こん (Kon): Comes from 今 (kon), meaning “this” or “now”
にち (nichi): Comes from 日 (nichi), meaning “day”
は (wa): A particle marking the topic of the sentence

Over time, the greeting was shortened to just “こんにちは” (konnichiwa), with the final は (wa) pronounced with a falling intonation to indicate it’s a greeting rather than a question.

This evolution showcases how language can simplify over time while retaining its essential meaning and function.
